Abstract

PURPOSE:To store a DTMF signal automatically into RAM when power is applied again even in the case of power failure by coding the DTMF signal representing a telephone number recorded on a recording medium and storing the coded signal to the RAM at application of power. CONSTITUTION:A DTMF detection transmission circuit 5 codes a DTMF signal representing a telephone number of a communication opposite party recorded on a cassette tape into a binary signal. Then a control means 10 stores the DTMF signal coded by the circuit 5 to a RAM 11 at application of power of the telephone set. Thus, even when a telephone number stored in a telephone number storage area of the RAM 11 is lost by power interruption of the telephone set, the DTMF signal representing the telephone number recorded on the cassette tape at application of power is coded automatically under the control of the means 10 and stored in the RAM 11. Thus, a backup use power supply is not required and the cost of the telephone set is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an answering machine for recording / reproducing a voice signal from a communication partner via a magnetic recording medium.

[0002]

2. Description of the Related Art Conventionally, an answering machine has generally been equipped with a tape deck for recording / reproducing a voice signal via a cassette tape. By recording the audio signal transmitted from the device on the cassette tape, the message from the other party is transmitted to the user of the device.

Further, in the above answering machine,
There is a function that stores the telephone number of the other party in the speed dial memory or one-touch dial memory in accordance with the above-mentioned answering machine function, enabling convenient telephone communication for the user of the device. There is.

[0004]

However, in the case of the answering machine in which the telephone number of the communication partner is stored in the speed dial memory or the one-touch dial memory as in the above-mentioned conventional method, the power supply of the apparatus is lost due to a power failure or an unexpected situation. When this is cut off, the telephone number of the communication partner stored in the memory is erased accordingly. For this reason,
The user of the device must again perform the operation of storing the telephone number of the communication partner in the memory. Further, in recent years, an answering machine having a backup battery has been proposed in order to avoid the disappearance of the telephone number due to the power interruption as described above, but such an answering machine has a relatively low cost. Since a backup battery must also be provided in accordance with the tape deck for the voice mail function, which causes an increase in the recording capacity, there is a problem in that the cost of the device increases significantly.

[0005]

In order to solve the above-mentioned problems, an answering machine according to the present invention comprises a magnetic recording / reproducing means for recording / reproducing a voice signal from a communication partner via a magnetic recording medium. The following means are taken in an answering machine having a storage means for storing a coded telephone number of a communication partner.

That is, the magnetic recording / reproducing means is adapted to record the telephone number of the communication partner as a DTMF signal on the magnetic recording medium, and the DTMF detecting / transmitting means for encoding the DTMF signal and the power source. DT which is the telephone number of the communication partner recorded in the magnetic recording / reproducing means at the time of input.
And a control means for storing the MF signal in the storage means via the DTMF detection and transmission means.

[0007]

According to the above construction, the telephone number of the communication partner is recorded in the magnetic recording medium as a DTMF signal, and the communication partner recorded in the magnetic recording medium is controlled by the control means when the power is turned on. DTMF signal, which is the telephone number of
It is adapted to be coded by the MF detection and transmission means and stored in the storage means. Therefore, even if the power of the device is cut off due to a power failure or the like, simply by turning the power on again, the telephone number of the communication partner is automatically stored in the storage means. There is.
